OILING SYSTEM.

Application filed May 23,

To all whom it may concern.

Be it known that I, GFUSTAF M. ANnERsson, a subject of the King ofSweden, residing at Waterloo, in the county of Blackhawlt and State ofIowa, have invented certain new and useful Improvements in OilingSystems, of which the following is a specification.

My invention relates to oiling systems, and more particularly to suchsystems as apply to centrifugal separators. and the like.

The object of my improvement is the provision of means for directing theoil in a cent:' fug'al separator through a filtering element and causethe filtered oil to pass through the bearings of the separator and 0'her parts to be oiled, then re-conducted to the filtering medium.

other objects will appear hereinafter.

in embodiment of my invention is shown in the accompanying drawing,forming a part of this specification, and in which the figure representsa central section of a cream separator, or the like, embodying myinvention.

In the drawing I have illustrated a casing; 1 in which is mounted avertical spindle 2 carrying at its top a separator bowl 3 and mounted insuitable bearings The spindle 2' is provided with a worm meshing with aworm wheel 5, and the latter is mounted on a drive shaft 6. The casino 1is provided with a fillingopening 7 and a drain open ing' controlled bya valve 8.

The casing 1 is formed so that one of its ides 9is close to andsubstantially concenr'. h a portion of the worm wheel 5 so worm wheeltravels in the direcor he arrow 10 oil will be carried up from the lowerportion of the wheel and discharged by centrifugal force in thedirection of arrow 11 against the side 12 of the casing. This oil willthen descend by gravity down the side 12 and fall on a filter element13. This filter material may be of felt, or any other desirablesubstance suitable for properly cleaning the oil. The material 13 ispreferably held away from the bottom of the oil well 14 by a perforatedplate 15. The perforated plate may be woven wire or material perforatedso that the oil may pass freely through it after leaving material 13.The oil level in the eas- 1 should not be above the plate 15.

In the bottom at one edge of well 1ais Specification of Letters Patent.

a passage 16 which leads both to an opening 17 adjacent the spindle 2and to a passage 18 down through or around bearing 4; and up to anopening 19 adjacent the lower part of the worm wheel 5 so that thepassage of oil from well 14 may be down through bearing 4 and over thetop of same to the worm wheel 5 as the latter draws the oil up againstside 9 of the casing 1.

With this construction it will be apparent that most of the oil passesthrough the filter 13 as it circulates in the manner above mentioned.Some of the oil will, of course, fall before reaching side 12 and engagethe worm on spindle 2 and fall directly to the bottom of the casingabovebearing 4e.

lVhile I have illustrated and described the preferred form of myinvention, I do not desire to be limited to the precisedetails setforth, but desire to avail myself of such variations and changes as comewithin the scope of the appended claims.

I claim l. A centrifugal separator comprising a casing having a well inits lower side; a wheel in the casing adapted to lift oil from the lowerside of the casing and direct such oil against the casing above saidwell, said well being adapted to receive substantially all the oildirected against said casing; a support across said well; and filtermaterial on said support in said well, there being av passage from saidwell to a position adjacent the lower part of said wheel.

2. A centrifugal separatorcomprising a casing; a bearing in said casing;a well above said casing with a passage leading from said well alongsaid bearing for conducting oil to the latter; filter material in saidwell; and means for lifting" oil from the bottom of said casing adjacentsaid bearing and delivering said oil to said well.

A centrifugal separator comprising a casing; a bearing in said casinghaving a passage extending along opposite sides thereof; a well at oneside of Said bearing with a passage opening into the passage as sociatedwith said bearing; a filter in the upper portion of said well; and awheel in said casing adapted to lift oil from adjacent said bearing anddischarge said oil against the interior of the casing above said well.

4. A centrifugal separator comprising a casing; a. bearing in saidcasing; a shaft in said bearing, there being a passage along the shaftin the bearing; a well connected with in said reservoir; a Well in thecasing above one endof said passage; means for moving oil in saidreservoir and communicating the oil from the other end of said passagewith the other end of said passage; a Wheel to said Well; and a filterin the Well. running in the oil of said reservoir and 5 5. A centrifugalseparator comprising a adapted to move said oil to said Well; and 15casing having an oil reservoir at its bottom a filter in the Well. side;a bearing in said casing; a substan- In testimony whereof I have signedmy tially vertical shaft in said bearing, there name to thisspecification on this 19th day being a passage in the bearing-along saidof May, A.
